SPECIFICATION forming part of Letters Patent No. 356,115, dated January18, 1887.

(No model.)

To aiZ whom it may concern:

Be it known that I, EDWIN FROTHINGHAM,

a citizen of the United States,residing at.

Boston, in the county of Suffolk and State of Massachusetts, haveinvented an Improvement-in DoonStops, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, making part of this specification, in which- Figure 1 is aperspective view, showing my improved door-stop applied to thebase-board of a room. Fig. 2 is a side elevation of my door-stop. Fig. 3is a front elevation of the same. I

My invention has for its object to provide a cheap, simple, and durabledoor-stop which will possess a greater amount of elasticity and yield toa greater extent than those now in common use, whereby the door instriking the,

same is relieved from the shock or jar experienced with the ordinarydoor-stop; and to this end my invention consists in a door-stop composedof a single piece of wire bent to form a helical or spiral spring, andhaving at itsa inner end a projecting portion adapted to enter thebaseboard of a room, and bearing at its a right angle to form thestraight portion 0,

Fig. 2, which extends outwardly in line with the axis of the stop, andis preferably pro vided wit-h a scrcw-thread to enable the stop to bescrewed into the base-board B of the apartment, as seen in Figs l and2,in aproper position to intercept the door as it is opened, and preventthe contact of the door-knob with the wall.

If desired, the portion 0 may be smooth and be driven into ahole boredto receive it. It is obvious, however, that the portion 0 may bedispensed with entirely, and the wire spring be secured in place in anysuitable manner forinstance, by means of staples passed over the last orinner coil of the wire, and driven into the baseboard B. The outer endof the wire I) is bent outwardly to form a short-projecting port'ion,d,which is also, in line with the axis of the stop, and bears a button orknob, f, of hemispherical or other suitable shape, and preferablycomposed of rubber or other elastic substance to prevent the door frombeing marred or injured by contact therewith, the portion (1 of the wirebeing, preferably, provided with a screw thread, and being screwed intothe center of the back of thebutton or knobf, whereby the latter issecurely fastened upon the end of the wire. This button or knob receivesthe'impact of the door as the latter is swung open against it, and itwill be obvious that the helical or spiral wire spring above describedwill yield to a much great-er extent than an ordinary door-stop,

thus effectually preventing any unpleasant jar 'or concussion from beingcommunicated to the door,which is an important consideration, especially where a portion of the door is composed of glass, while theforce of the blow is taken up so gradually and easily that noise isavoided, thus presenting many advantages hitherto unaltained.

What I claim as my invention, and desire to secure by Letters Patent, is

The herein-described door-stop,composed of a single piece of wire bentto form a helical or spiral spring, and having at its inner end aprojecting portion adapted to enter the baseboard of aroom, and hearingat its outer end a button or knob for contact with the door,substantially as set forth.

\Vitness my hand this 13th day of November, A. D. 1886.

EDlVIN FROTH INGHAM.
